FASTENER FOR LIDS F CASES.

Application filed January To all 107mm it may concern:

Be it known that we, RICHARD HENRY Ronnnrs and PERCY NIOHOL KINoswnnL, both citizens of the Dominion of New Zealand, and residing at Farmley Tyas, Te Atatu, Henderson, and Golf Road, Epsom, Auckland, respectively, have invented certain new and useful Improvements in Fasteners for Lids or Cases, of which the following is a specification.

This invention relates to means for fastening lids or" cases and more particularly the lids of fruit cases, and to that kind or" fastening means comprising a pin or pins rotatable in the end of the case and in a slot or slots in the lid and having a substantially right angled member or members adapted to engage and fasten the lid.

According to the present invention, in fastening means of the said kind, the head or right angled member of the pin or of each pin is adapted, when turned toward the locked position, to bear down upon the lid with increasing pressure as it is further turned toward said position. This action of the pin can be effected in various ways, for example, by suitably sloping the sur face on which the right angled member bears while being turned into the locked position, or by arranging the shank of the pin so that the axis of turning is not perpendicular to the bearing surface the latter being parallel to the lid surface, or by providing the pin with a screwed shank adapted to draw the pin bodily downward as it is turned into locked position, and thereby to force the right angled member with increasing pressure against the lid.

The drawing herewith illustrates the invention:

Figure 1, is a perspective view of a case embodying the invention,

Fig. 2, is a front elevation,

Fig. 3, a longitudinal sectional elevation, and

Fig. 4, a plan showing one embodiment of the invention,

Fig. 5, is a sectional elevation showing another embodiment of the invention,

Fig. 6, is a sectional elevation showing another embodiment of the invention, and

Fig. 7, is a perspective view showing two fasteners on a single case.

Referring more particularly to Figs. 1, 2,

Specification of Letters Patent.

3, andel the lid 1 of the case 2 has battens 3 and 4t fixed across the top at its ends, and slots or notches 5 and 6 are made through the lid 1 and the battens 3 and a respectively. A nail 7 having a head 8 of large diameter is driven intothe end 9 of the 'case 2 and is engaged by the slot 6, while the head 8 retains the lid.

A pin 10, turnable in a hole 11 made in the end 1 of the case 2, has a right angled member 13 at its lower end engaging the top of a mortise 14, and at its upper end is engaged by the slot 5, where another right angled member 15 is sunk in a recess 16 formed in the batten 3, and engages the same. The member 15 is capable of being turned into line with the notches 5 when the lid may be raised clear of the pin and withdrawn from the nail 7.

A mortise 17 is made in the end 9, and the case is readily handled by passing the fingers into the mortises l4 and 17.

Referring to Fig. 5, the lower end of the pin 10 is riveted upon a. washer 18, which engages the top of the mortise 14.

Referring to Figs. 6 and 9, the lower end of the pin 10 is screw threaded and screwed into the end 12 of the case, so that when the member is turned rearwardly into the position shown the said member bears down upon the lid with increasin pressure as it is further turned toward the locked position.

For a similar reason the bottom 21 of the recess 16 is made to slope as shown in Figs. 2 and 3, and in Fig. 5 the pin 10 is made to slope as shown so that its axis of rotation is not perpendicular to the bottom of the recess on which the member 15 bears, said bottom being parallel to the lid surface and in each case the member 15 when turned rearwardly will rip the lid with gradually increasing pressure, and when turned forwardly gives clearance to the lid when the case is to be opened.

A label 24 as shown by dotted lines in Fig. 5 can be pasted over the member 15 to he batten 3 and end 12 to show that the case has not been opened by an unauthorized person. The label may bear the trade mark of the producer.

What we do claim and desire to secure by Letters Patent of the United States is 1. A fastener for lids of cases, comprisother end of the case ing a headed nail; projecting from one end of n czise and engaged by a notch made in one end of a lid, and it pin turnable in the and having a right angled member which is engaged by a notch in the other end of the lid and when the pin is turned toward the locked position beers down upon the lid with increasing pressure as it is further turned toward the locked position.

2. rustener for lids of cases, ing a headed nail projecting from one end of :1 case and engaged by a notch made in one o -;l of :1 lid and a pin turnzihle in the other end of the case having a right angled member at its lower end within a mortise formed in the end of the case, and having another ght angled member at its upper end which is engaged by a notch in the other end of the lid and when the pin is turned toward the locked position hen-rs down upon compristhe other end of the gled member ly ng the lid with increasing pressure as it is further turned toward the locked position.

3. A fastener for lids of cases, comprising a heeded nail projecting irom one end of a case and engaged by a notch made in one end of a lid a pin turnahle in the other end of the case and having it right angled member and being engaged by a notch in lid, the said right 211 7 in a sloping recess formed in the lid, so that it bears down upon the lid with. increasing pressure as it is turned toward the locked position.

In testimony whereof we have signed our names to this specification in the resence of two witnesses. V V
